Aromatics Recovery Training Course

Consultant/Trainer: Thomas Diehl & Brigitte Sölla

The Petrogenium Aromatics Recovery / Extraction / Extractive Distillation course provides insight into technological fundamentals and will raise awareness of design aspects to refinery / petrochemical plant staff on optimized operation of their aromatics recovery facilities. Over many years the Petrogenium experts gathered deep technical expertise in the operation, optimization and troubleshooting of all extraction / extractive distillation technologies and their associated equipment. This knowledge and resulting best practices were collected and built the foundation for the course.


This Petrogenium course can be tailored for awareness/inexperienced staff, for intermediate and for experienced personnel. Furthermore the course can be customized for a specific refinery, plant or unit. The option for post-course consultancy/help-desk support is also available.

Participants may include: refinery/petrochemical technologists, process engineers & economists and operational staff who work with Aromatics Recovery Units with Extractive Distillation or LL-Extraction technology.
